Silica Gel for Edible Oil Storage Stabilization
Classification :
Adsorbent Silicon Dioxide
Keywords :
Silica Gel for Edible Oil Storage Stabilization
PRODUCT DETAILS
1. Product Description
This is a food-grade hydrophobic modified silica gel exclusively for storage stabilization, with INS E551. It is a white powder, odorless and tasteless, compliant with FDA GRAS, EFSA E551 and USP standards, with a SiO₂ content of ≥99%. It can target and adsorb pro-oxidants, free moisture and trace active impurities that cause storage deterioration in edible oil, greatly improving oil storage stability, retarding rancidity, delamination, turbidity and flavor deterioration with no secondary odor. It is suitable for pre-storage treatment and long-distance transportation protection for all edible oils worldwide.

3. Application Description
Its core function is improving edible oil storage stability and retarding storage deterioration. It can efficiently adsorb impurities that cause oil deterioration (free moisture, peroxides, pro-oxidants such as aldehydes and ketones, trace metal ions) in soybean oil, rapeseed oil, olive oil, peanut oil, animal fat and blended oil, inhibit the auto-oxidation reaction of oil, retard storage problems such as rancidity, delamination, turbidity, flavor fading or off-flavor, and greatly extend the shelf life and conventional storage period of oil products.
Suitable for pre-storage pretreatment of various edible oils, finished barreled oil stabilization, long-term storage of bulk oil and long-distance transportation protection via global sea/land freight, it does not affect the subsequent processing and edible properties of oil products.
4. Factory Advantages
We hold the proprietary patent for hydrophobic and antioxidant modification of silica gel for edible oil storage stabilization, and are equipped with oil oxidation stability testers and water activity analyzers, with an exclusive storage stability performance control system established. Our GMP food-grade production workshops have obtained ISO22000 and FDA GRAS certifications, and our products are exported to more than 50 countries. We have rich experience in providing customized solutions for long-distance transportation and long-term storage for overseas edible oil enterprises. With a lead time of 5-10 working days, we offer storage stabilization process adaptation guidance and optimized storage period solutions for oil products.
5. Shipping & Packaging
- Standard Packaging: 20/25kg paper-plastic composite bags with built-in high-activity hydrophobic moisture-proof agents to prevent moisture absorption, which may impair the storage stabilization and adsorption performance of the product.
- Storage & Transportation Requirements: Store in a cool, dry, sealed and dark place, avoid high temperature and humidity. Non-hazardous chemical, available for global sea and air freight.
- Labeling Norms: Clearly marked with storage stabilization-specific attribute, storage life extension rate and moisture adsorption rate. Multilingual labels and oil oxidation stability test reports can be affixed as required by international customers.
6. Frequently Asked Questions
Q: Will the addition of this product affect the subsequent processing (e.g., frying, refining) of edible oil?
A: No. The product becomes an inert solid powder after adsorbing impurities and can be removed via conventional filtration processes as needed. Even if a small amount remains in the oil, it is a food-grade inorganic powder that will not react or leach during subsequent processing such as frying and refining, nor affect processing effects and oil quality.
Q: Is the stabilization effect still significant in the scenario of long-distance sea transportation (high humidity, large temperature difference)?
A: Yes. The product’s hydrophobic and antioxidant adsorption performance is optimized for the high-humidity and large temperature difference environment of sea transportation. It can efficiently adsorb trace free moisture generated in oil due to environmental changes and newly formed pro-oxidants during transportation, effectively preventing oil deterioration in transit and ensuring oil transportation quality.
